Abstract:
Sound environmental management includes the proper management of waste. This chapter reviews the basic rules of good management practice illustrated by some examples from chlorine derivatives production and gives the main considerations governing the Best Available Techniques for organochlorine waste thermal treatment. A review of the main degradation pathways of organochlorines - dispersal, distribution, degradation pathways, and environmental half-lives - demonstrates a very large range of characteristics, justifying the need for a separate study for each substance. Finally, the paper examines the latest developments in organochlorine contaminated site remediation technology.

Abstract:
ABSTRACTThe phylumChloroflexicontains several isolated bacteria that have been found to respire a diverse array of halogenated anthropogenic chemicals. The distribution and role of theseChloroflexiin uncontaminated terrestrial environments, where abundant natural organohalogens could function as potential electron acceptors, have not been studied. Soil samples (116 total, including 6 sectioned cores) from a range of uncontaminated sites were analyzed for the number ofDehalococcoides-likeChloroflexi16S rRNA genes present.Dehalococcoides-likeChloroflexipopulations were detected in all but 13 samples. The concentrations of organochlorine ([organochlorine]), inorganic chloride, and total organic carbon (TOC) were obtained for 67 soil core sections. The number ofDehalococcoides-likeChloroflexi16S rRNA genes positively correlated with [organochlorine]/TOC while the number ofBacteria16S rRNA genes did not.Dehalococcoides-likeChloroflexiwere also observed to increase in number with a concomitant accumulation of chloride when cultured with an enzymatically produced mixture of organochlorines. This research provides evidence that organohalide-respiringChloroflexiare widely distributed as part of uncontaminated terrestrial ecosystems, they are correlated with the fraction of TOC present as organochlorines, and they increase in abundance while dechlorinating organochlorines. These findings suggest that organohalide-respiringChlorofleximay play an integral role in the biogeochemical chlorine cycle.

Abstract:
Hydrophobic organochlorine contaminants were surveyed in net plankton from 33 lakes in southern Ontario. Organochlorines were detected in all lakes. The relative concentrations of 12 common organochlorines were generally similar, suggesting that they derive from a common source, probably atmospheric transport. Variability in relative abundances of these contaminants increased with contaminant concentration, while contaminant concentration was related to plankton biomass, total phosphorus, and conductivity. Lakes with low plankton biomass had high organochlorine concentrations in that biomass, indicating that a large portion of the variation among lakes in the concentration of contaminants in plankton can be ascribed to variable planktonic biomass. This negative relationship with plankton biomass, or biomass dilution effect, was strongest for the more hydrophobic and refractory compounds.

Abstract:
Abstract Fillets from 11 species of commercial fish from the Great Lakes were analyzed for residues of 39 polychlorinated biphenyl (PCB) congeners and 24 other organochlorine compounds. Eel and trout contained the highest amount of PCB (753 and 633 ppb wet weight, respectively) and other organochlorines (607 and 1404 ppb, respectively); perch and carp contained the lowest residues. The pentaand hexachlorinated PCBs were the major congeners in all species except whitefish, in which the tetrachlorinated congeners predominated. Toxaphene was the most abundant organochlorine pesticide in trout; p,p′ -DDE was the major component of this class in eel. Residue concentrations in commercial carp were compared with residues present in carp from a fishery closed to commercial operation. Although both PCB and organochlorine pesticide levels in carp were among the lowest for all commercial fish samples, levels from the contaminated area were among the highest.

Abstract:
Sediment samples from the North Sea and the Skagerrak were analyzed for organochlorine pollutants. Standardisation for organic carbon content of sediments proved to be a suitable tool for comparison of pollution of different sea regions. Relatively high contaminant concentrations were found in coastal regions of the southern North Sea, while standardised organochlorine concentrations in the Skagerrak were almost at baseline level. In addition to the major inputs via rivers and the atmosphere, ocean incineration of hazardous wastes was identified as a probable source of organohalogen pollution. Although the production and use of certain organochlorines have been restricted in most North Sea states, depth profiles from the Skagerrak indicate that deposition of these contaminants has increased until recently. This trend will possibly continue since only a very small proportion of all persistent organochlorines produced in Western Europe in the past has already reached the sea. As a consequence, no persistent and bioaccumulable organics, like most organohalogens, should be allowed to enter the sea in the future. This, in many cases, will necessitate not only better filter techniques, but a dramatic reduction of organic chemical production itself.

Abstract:
Abstract Organochlorines have diverse structures and applications and are included in the list of persistent organic pollutants (POPs) due to their toxicity and environmental persistence. The reduced capacity of conventional wastewater treatment plants to remove these compounds encourages the development of cost-effective and efficient remediation approaches. Fungal biotechnology can contribute to the development of these technologies through their enzymatic machinery but faces several drawbacks related to the use of dispersed mycelium. In this sense, investigations concerning the degradation of organochlorines using immobilized fungi demonstrated an increase in contaminant removal efficiency compared with degradation by free cells. Despite this interest, the mechanisms of immobilized fungi have not been comprehensively reviewed. In this paper, recent advances of laboratory and field studies in organochlorine compounds removal by fungi are reviewed, focusing on the role of immobilization techniques. Firstly, the mechanisms of organochlorines bioconversion by fungi and the factors affecting enzyme activity are elucidated and discussed in detail. Then, the main targeted compounds, fungi, technics, and materials used for immobilization are discussed, as well as their advantages and limitations. Furthermore, critical points for future studies of fungi immobilization for organochlorine removal are proposed.

Abstract:
Abstract A survey was conducted from 1993 through 1995 to monitor organochlorine pesticides and their metabolite residues in milk available in local Hong Kong markets. Of 252 samples analyzed, including pasteurized milk, fresh milk, and raw milk, 42 contained organochloride pesticide residues at levels exceeding the Extraneous Maximum Residue Limits of the Codex Committee on Pesticide Residues. DDE and HCH isomer levels were substantially higher than those found in a 1984–1987 survey, probably because the source of cow’s milk has shifted from local dairy industries to mainland China over the past decade. Although organochlorine pesticides such as DDT and HCH have been banned in China since 1983, residues of such compounds may still persist in the environment and cause contamination through the food chain.

Abstract:
Abstract Organochlorine chemicals and lead are environmental exposures that have endocrine disrupting properties (EDCs) which interfere with many aspects of hormone action. Childhood and adolescence are windows of susceptibility for adverse health effects of EDCs. Our ongoing study, the Russian Children’s Study (RCS), is one of the few longitudinal studies investigating the impact of EDCs on growth and puberty in boys. It is conducted in the historically contaminated city of Chapaevsk, in the Samara region. The study focuses on evaluating the associations of persistent organochlorine chemicals and lead with growth and pubertal timing. At enrollment in 2003–2005, we collected blood from 516 boys at ages 8–9 years to measure dioxins, furans, polychlorinated biphenyls (PCBs), chlorinated pesticides and lead. At enrollment and at annual visits through the ages of 18–19 years, a physician performed physical examinations that included pubertal staging and testicular volume measurements. We review the history of Chapaevsk as a research site and summarize published RCS data on the association of peripubertal serum concentrations of organochlorines and blood lead levels with growth, pubertal onset and sexual maturity. Overall, we found that persistent organochlorines and lead negatively affected growth during puberty. Our results also suggest that total toxic equivalents (TEQs), dioxin-like compounds, organochlorine pesticides and lead may delay, while nondioxin-like-PCBs may advance, the timing of male puberty. These findings promoted remediation programs in Chapaevsk, with improvement in health indicators, resulting in Chapaevsk being designated a member of the World Health Organization (WHO) network “Healthy Cities” in 2015.

Abstract:
Pentachlorophenol, (PCP) is an organochlorine compound which was first developed in the 1930’s. PCP is said to be the most toxic of the chlorophenols and is classified as a hazardous substance and a probable human carcinogen. PCP has proven to be cytotoxic to a number of cell lines translating to its effect on various organs. The aim of the study was to assess organochlorine-induced hepatotoxicity in a mechanistic manner using an in-house developed procedure. Also, the possible hepatoprotective effect of methanolic extracts of the bark of two medicinal plants, Burkea africana (BA) and Syzygium cordatum (SC), as well as the known hepatoprotective agent, N-acetyl cysteine (NAC), were investigated. In addition to PCP, two of its major metabolites, tetrachloro-1,2-hydroquinone (TCHQ) and tetrachloro-1,4-benzoquinone (TCBQ) were also evaluated. A hepatocarcinoma cell line (HepG2) was used to investigate the effect of these compounds on different parameters of cellular function. Cytotoxicity was assessed using the neutral red uptake assay. Cytochrome P4501A1 (CYP1A1) activity was determined using ethoxy-resorufin-O-deethylation as surrogate. Generation of reactive oxygen species (ROS) was investigated by measuring dichlorofluorescein diacetate cleavage. Effects on mitochondrial membrane potential were determined using JC-1 staining, whilst necrosis was investigated by assessing plasma membrane integrity using propidium iodide (PI)staining. The degree of apoptotic death was determined by quantifying caspase-3 activity. Assays were repeated with an additional 1 h pre-treatment of the cells with either NAC, SC or BA in order to investigate whether these compounds were able to protect against the toxicity induced by PCP and its metabolites. The IC50 values of PCP, TCHQ and TCBQ were 68.0, 144.0 and 129.4 μM, respectively. All three test compounds induced CYP1A1 activity with PCP being the most potent. TCBQ produced extensive ROS generation. TCHQ also induced ROS generation, whilst PCP appeared to have no significant effect on ROS generation. All test compounds caused mitochondrial depolarization. None of the test compounds caused an increase in necrotic cell death. PCP, TCHQ and TCBQ had negligible effects on apoptosis. Both SC and BA alleviated the toxic effects observed in cells treated with PCP. Minor increases in viability occurred in cells pre-treated with plant extracts prior to exposure to both metabolites. NAC, as well as both plant extracts, greatly reduced CYP 1A1 activity induced by PCP. NAC, SC and BA exacerbated CYP1A1 induction in cells exposed to concentrations of TCBQ and TCHQ that initially produced little or no effect on CYP1A1 activity. Contrarily, decreased CYP1A1 activity was observed in cells exposed to concentrations of TCBQ and TCHQ where extensive induction of CYP1A1 occurred. NAC, as well as both plant extracts, suppressed ROS generation in cells exposed to all test compounds. In cells exposed to PCP and TCBQ more extensive mitochondrial depolarization was seen when pre-treated with NAC and plant extracts than when exposed to the compounds alone. Negligible effects were seen in pre-treated cells exposed to TCHQ. BA and SC caused increases in necrotic death in cells exposed to the test compounds. NAC, BA and SC had negligible effects on the changes in caspase-3 activity induced by the test compounds. From the results it is proposed that PCP induces its own metabolism by increasing CYP1A1 activity. It also causes mitochondrial insult which could lead to the opening of the mitochondrial permeability transition pore and subsequent release of cytochrome C, activation of caspases and eventually apoptotic cell death. With regard to TCHQ and TCBQ, results suggest that extensive ROS generation caused damage to various cellular macromolecules and that this could be the main cause of their toxicity. NAC, SC and BA appeared to alleviate toxicity in certain instances. Further investigation is required in order to assess them as possible hepatoprotective agents. Copyright

Abstract:
This study evaluated levels for organochlorine pesticides (DDTs, HCHs, Heptachlors, Aldrins and Endosulfanes), their residues, polychlorinated biphenyls (PCB) and poly aromatic hydrocarbons (PAH) in water samples of Adriatic Sea, Albanian part. Water stations were chosen near the main river estuaries of Albania (Vjosa, Semani, Shkumbini, Erzeni, Mati and Buna rivers). These rivers have catchment areas that cover almost all Albania. First, agricultural, industrial and urban waste is transported in these rivers and after that they finished in Adriatic Sea. Water samples were analyzed for a five-year period from February 2015 to December 2019. Liquid-liquid extraction was used to isolate chlorinated pollutants and a florisil column was used for clean-up procedure. Analysis of organochlorine pesticides (according to Method EPA 8081B) and 7 PCB markers was realized using GC/ECD and RTX-5 capillary column. The PAHs were isolated by liquid-liquid extraction technique and after sample concentration qualitative and quantitative analyses were performed by the GC/FID technique. Organochlorine pollutants were detected for all stations of Adriatic Sea because of new arrivals by agricultural and industrial activity in river basins. The highest levels were found near Shkumbini and Semani estuaries due to impact Myzeqeja agricultural area. New arrivals from water irrigation and rainfall influence in found levels. Degradation products of pesticides and volatile PCBs were found at higher levels for all samples analyzed. The levels of some individual organochlorine pesticides were higher than EU and Albanian norms for Semani and Shkumbini rivers. Also, PAHs were found at higher levels for Semani River because of extracting-processing industry in Patos-Marinza area. Monitoring of organic pollutants in water of Adriatic Sea should be continuous because of its importance in fishing, tourism, recreation and Albania economy overall.

Abstract:
The overall theme of this project was to increase the speed of analysis for monitoring pesticide residues in food. Traditionally, analytical methods for multiple pesticides are time-consuming, expensive, laborious, wasteful, and ineffective to meet critical needs related to food safety. Faster and better methods were needed to provide more cost-effective detection of chemical contaminants, and thus provide a variety of benefits to agriculture. This overarching goal to speed and improve pesticide analysis was successfully accomplished even beyond what was originally proposed by the investigators in 1998. At that time, the main objectives of this project were: 1) to further develop a direct sample introduction (DSI) device that enables fast sampling and introduction of blended-only agricultural products for analysis by gas chromatography (GC); 2) to evaluate, establish, and further develop the method of simultaneous pulsed flame photometric detector (PFPD) and mass spectrometry (MS) detection for enhanced pesticide identification capabilities; and 3) to develop a new and novel MS pesticide analysis method, based on the use of supersonic molecular beams (SMB) for sampling and ionization. The first and third objectives were successfully accomplished as proposed, and the feasibility of the second objective was already demonstrated. The capabilities of the GC/SMB-MS approach alone were so useful for pesticide analysis that the simultaneous use of a PFPD was considered superfluous. Instead, the PFPD was investigated in combination with an electron-capture detector for low-cost, simultaneous analysis of organophosphorus and organochlorine pesticides in fatty foods. Three important, novel research projects not originally described in the proposal were also accomplished: 1) development of the quick, easy, cheap, effective, rugged, and safe (QuEChERS) method for pesticides in foods; 2) development and optimization of a method using low-pressure (LP) GC/MS to speed pesticide residue analysis; and 3) innovative application of analyte protectants to improve the GC analysis of important problematic pesticides. All of the accomplishments from this project are expected to have strong impact to the analytical community and implications to agriculture and food safety. For one, an automated DSI approach has become commercially available in combination with GC/MS for the analysis of pesticide residues. Meanwhile, the PFPD has become the selective detector of choice for the analysis of organophosphorus pesticides. Great strides were made in SMB-MS through the manufacture of a prototype "Supersonic GC/MS" instrument, which displayed many advantages over commercial GC/MS instruments. Most notably, the QuEChERS method is already being disseminated to routine monitoring labs and has shown great promise to improve pesticide analytical capabilities and increase lab productivity. The implications of these developments to agriculture will be to increase the percentage of food monitored and the scope of residues detected in the food, which will serve to improve food safety. Developed and developing countries alike will be able to use these methods to lower costs and improve results, thus imported/exported food products will have better quality without affecting price or availability. This will help increase trade between nations and mitigate certain disputes over residue levels in imported foods. The improved enforcement of permissible residue levels provided by these methods will have the effect to promote good agricultural practices among previously obstinate farmers who felt no repercussions from illegal or harmful practices. Furthermore, the methods developed can be used in the field to analyze samples quickly and effectively, or to screen for high levels of dangerous chemicals that may intentionally or accidentally appear in the food supply.
