Abstract:

Manganese is considered as an essential element for man and other animals. Although it is one of the trace elements least toxic to mammals, man-made pollution related to the steel industries and exposure to the mining of manganese ore represent potential hazards to organisms in these areas.One of the target organ systems of manganese is the central nervous system (Beliles, 1975). Intake of its metal dust can lead to chronic manganese poisoning resembling Parkinson’s disease (Ferraz, et.al., 1988). Symptoms of this disease have been observed in human after prolonged chronic exposure to manganes

Symptoms of HM poisoning can be life-threatening and not only cause irreversible damage to humans and other organisms; but also significantly reduce agricultural yield.

The acute (24 h) LD50 values of Mn following intraperitoneal, intramuscular, subcutaneous and oral administrations of MnCl2 in seven-day-old chicks were 21.3 mg kg-1, 28.1 mg kg-1, 28.1 mg kg-1 and 469.5 mg kg-1 body weight of Mn, respectively. Signs of Mn poisoning appeared in the chicks within 2 min and 13 min after parenteral administration and within 20 min and 32 min after oral administration

Abstract:

Manganese oxide-supported palygorskite (MnOx/PG) catalysts are considered highly efficient for low-temperature SCR of NOx. However, the MnOx/PG catalyst tends to be poisoned by SO2. The effect of SO2 on activity of the SO2-pretreated poisoning catalysts under ammonia-free conditions was explored. It was determined that the MnOx/PG catalyst tends to be considerably deactivated by SO2 in the absence of ammonia and that water-washed regeneration can completely recover activity of the deactivated catalyst. Based on these results and characterizations of the catalysts, a reasonable mechanism for th

Abstract:

Our work focused on the impact of chronic lead acetate and manganese chloride poisoning on renal function in Wistar rats. It also tested the efficacy of the essential oil extracted from (Mentha spicata) spearmint in reversing these effects by treating previously poisoned rats with a daily intraperitoneal injection of 0.1 ml HEM/kg over a 21-days period. Analysis of this essential oil through gas chromatography coupled with mass spectrometry revealed that the main components are: carvone (42.2%), menthone (20.89%), piperitenone (17.41%) and isomenthone (7.99%).

Abstract:

In this study, the poisoning effect of CaO on activated carbon (AC)-based Mn-Ce catalysts was discussed. Loading CaO inhibited the catalytic activity of the catalyst and the NO conversion of the catalyst decreased from 69.5% to 38.2% at 75 °C. The amount of MnO2 in AC surface decreased in the process of loading CaO, which was detrimental to the Selective Catalytic Reduction (SCR) performance of the catalyst. The change of manganese oxide form inhibited generation rate for the chemisorption oxygen and NO2, which was the most critical reason for the decrease of catalytic activity. Besides, loade

Abstract:

Heavy metal and metalloid poisoning in the environment and food has piqued the public’s interest since it poses significant hazards to the ecological system and human health. In food, several metals, including cadmium (Cd), lead (Pb), mercury (Hg), tin (Sn), manganese (Mn), and aluminium (Al), and metalloids, including arsenic (As), antimony (Sb), and selenium (Se), pose a severe threat to human health. It is of utmost importance to detect even minute quantities of these toxic elements and this must be efficiently determined to understand their risk. Several traditional and advanced technologi

Abstract:

Manganese oxide-cerium oxide supported on titanate nanotubes (i.e., MnCe/TiNTs) were prepared and their catalytic activities towards NH3-SCR of NO were tested. The results indicated that the MnCe/TiNT catalyst can achieve a high NO removal efficiency above 95% within the temperature range of 150–350 °C. Even after exposure to a HCl-containing atmosphere for 2 h, the NO removal efficiency of the MnCe/TiNT catalyst maintains at approximately 90% at 150 °C. This is attributed to the large specific surface area as well as the unique hollow tubular structure of TiNTs that exposes more Ce atoms, whi

Abstract:

Excessive discharge of toxic metals into water surfaces as a result of increased production has become the main ecological problem due to the lack of efficiency of techniques that would deal with industrial liquid waste. These metals accumulate at high toxicity levels and cause a serious impact on aquatic organisms without a visible sign. They can cause poisoning or toxic effects even in lower concentrations. Therefore, these toxic heavy metals include cadmium, manganese, copper, lead, nickel, cobalt and chromium. They are highly toxic metals when they are brought into the body and have a dire
