Modern ecological and hygienic problems of the agricultural economy associated with development of pond fish farming

The materials on the study of the content of heavy metals and organochlorine pesticides in fish are presented. It has been established that the level of heavy metals and pesticides in fish is influenced by the territorial location of the pond production. Therefore, the content of lead, cadmium and mercury in the liver and gonads of carp was higher than the permissible values for fish growing in ponds located in the city limits near highways. The pesticides DDT and HCH were detected in the organs of fish in the territories of pond fish farming of farms. Residual concentrations of pesticides contained in fish did not exceed the maximum permissible levels. In order to safely consume fish grown near highways by the population, we recommend the removal of internal organs (liver and gonads) from fish products.

Consistent Organochlorinated Pesticides (OPC) Residues Contamination in Beans Consumed in Gombe Metropolis Nigeria

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.

BANNED ORGANOCHLORINE PESTICIDES RESIDUE STILL OCCUR IN CATTLE MILK FROM KHARTOUM STATE

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.
