This study assessed the concentration levels of five different pesticide residues in water and soil samples that were collected from river Ngadda in Jere bowl, Nigeria. Pooled samples from different locations within five villages were determined by using GC / MS SHMADSU (GC - 17A) with an electron capture detector (ECD) and standard operating procedures were followed. The pesticides (Hexachloro hexahydro dimethanonaphthalene, Dichlorodiphenyl trichloroethene, Cypermethrin, Chlorpyrifos and Dichlorvos) were analysed. Results obtained (µg / g for soil and µg / l for water) revealed a variation in mean concentration levels of the pesticide residues analysed. Bololo, ranged from 9.13 to 38.14 for soil and 1.01 to 15.01 for water. Dusuman; Soil (5.17 to 32.16) and water (5.17 to 32.16). Gongulon; soil (5.27 to 42.10) and water (1.03 to 5.07). Kachallari; soil (17.15 to 24.16) and water (1.11 to 3.7). Masu village; soil (13.13 to 32.19) and water (1.11 to 3.71). The concentration levels were observed to be at alarming levels higher than the maximum residue limits (MRLs) for surface water and soil as described by WHO. The occurrence of the pesticide residues in the river water and soil, are major threats to farmers that are depending on river water for their daily activities and irrigation farming, and the public that is consuming the farm produce. Hence, there are needs for monitoring of pesticides applications and their usage in the said study area and its environs.

The objective of this study was to investigate the effects of different sources of sulfur fertilizer either organic as plant residue (composite tea), animal residue (chicken manure) or inorganic fertilizer (potassium sulfate) or industrial waste water on the ionic contents of potassium , sodium , calcium , magnesium, and iron in roots and shoots of  broccoli plants (Brassica oleracea L. var. italic). As well as sulfur interactions: sulfur content, sulfur requirement, sulfur uptake, rate of transport sulfur from root to shoot and distribution of sulfur in broccoli plants. The obtained results showed that the  potassium, sodium, calcium, magnesium, and iron contents  in  growing plants in different types of soil is closely linked to the stage of plant growth as well as the plant organ  and the type of soil used and also on the type and concentration of various fertilizers. The sulfur interactions included changes: in the total sulfur content, sulfur requirements, sulfur uptake and rate of sulfur transport from root to shoot. As well as, the change in the distribution of the sulfur in different plant organs: roots and shoots. Above parameters relied mainly on the soil type and various treatments.
