A systematic study has been performed for determination of a range of organochlorine pesticides in the water, sediments and fish samples in the Macedonian part of the Lake Ohrid and its larger tributaries. The obtained results give an overview of the contamination levels of these problematic compounds (i) at their potential sources in the river mouths, (ii) in the potentially affected, species-rich littoral section of the lake, and (iii) in the muscle tissue of one selected fish species Barbus peloponnesius, Valenciennes, collected near the rivers’ deltas. The organochlorine pesticides measured in all three matrixes were: γ-HCH, ΣHCH (sum of α-isomer, β-isomer and δ-isomer), endosulfan (total of α and β endosulfan), DDT metabolites (p,p’-DDE, p,p’-DDD and p,p’-DDT). The range of the observed concentrations for p,p’-DDT was between 0.006 μg l–1 in the water samples from Daljan and St. Naum and 0.036 μg l–1 in the water from the Koselska River. The values for p,p’-DDT measured in dry sediment ranged from 0.121 μg kg–1 in the sample from St. Naum to 1.8 μg kg–1 in the dry sediment from the Velgoška River and between 0.553 μg kg–1 for total endosulfan and 5.982 μg kg–1 for p,p’-DDE of wet fish biomass. The most abundant of the detected organochlorine pesticides was the sum of DDT metabolic forms, i.e. p,p’-DDT, p,p’-DDE and p,p’-DDD. The detected concentrations are clearly below toxic thresholds and consequently severe effects on the endemic species of Lake Ohrid are not very likely.

Background: Pesticides application for controlling pests, has been a matter of debate for long time. In order to guarantee sustainable human health, this application should be monitored continuously. Materials and Methods: 65 samples of cattle milk were collected from different Khartoum state’s municipals; to assess the OCP residue, samples were extracted with petroleum ether and cleaned up using silica gel, then read out by GC equipped with FID. Result: Two pesticides belong to OCP were detected, Endosulfan (69.8%) and Heptachlor (92%); the detected concentration of the second one was outstanding, as all positive samples were above the MRL.

Pesticides Residue

Most of the locally consumed beans in our vicinity contain excess chemicals of pesticides residues which are harmful to humans and environmental hazards to ecosystem. Investigation of this study revealed contamination level of organochlorine pesticides residues in dried beans originating from Nigeria with a view to controlling them, it also studies crude fiber of beans showed that B4 has the highest fiber content, 27.85% and the order of decreasing value as B4, B5 , B1, B3 and B2. The least percentage of crude fiber was shown by B2 in all the beans samples analyzed. This study also investigated the pesticides residue components of the organochlorinated pesticides test. The presence of pesticide residues in all 14 types of organochlorine pesticides in beans is lower than a previously reported level. Despite this, the amount of organochlorine pesticides tested is more than the permitted levels of 0.01 to 0.2 mg/kg, indicating that the beans consumed in the Gombe metropolis included pesticide residues beyond the permissible limit.
