Abstract:

The study analyzed the effects of pesticides on selected vegetable crops grown in Abakaliki, Ebonyi State Nigeria. The pesticide Dichlorvos (DD Force) was used to treat sites planted with Amaranth, cucumber, and okra. Soil and vegetable samples were randomly collected after 30 days of incorporation and tested for traces of chloride and phosphate. The results of the analysis showed that amaranth, cucumber, and okra residue concentration exceeded the maximum residual limit. Chloride and phosphate residues exceed the Maximum Residue Limit in vegetable crops. The amount of chloride in the soil sam

Abstract Within the scope of the amendment of the Radiation Protection Ordinance, it became necessary to lay down new limit values, as a result of both the modifications made in the stipulations of the EU directives, and improvements in the level of scientific and technological advancement. This led, at the same time, to the necessity of recalculating the permitted levels for activity concentrations in exhaust air from applications involving isotopes (mostly from medical installations). The following article provides an overview of the approach applied in the recalculation of the permitted act

Boreholes have traditionally been one of the sustainable water sources for domestic use. However, in Kano state, Nigeria, some of these boreholes have been drilled close to soak ways or pit latrines without considering the possibility of water contamination.

Factors affecting the permissible limits of sludge mixture circulation rate are given for airlift reactor-clarifier with a suspended layer. The upper limit of the circulation rate is justified as a function of some geometric dimensions of the bioreactor and the hydraulic load on the clarifier to comply with conditions of a suspended layer existence. The lower limit of the circulation rate was obtained on the basis of two conditions: the duration of the active sludge stay in anoxic conditions and the observance of recommended rates in the construction in order to avoid the settling of active sl

However, this advancement raises new questions as the analytical functions previously used to describe the cutter engagement will no longer be valid along the elliptic path.
