Cytogenotoxicity effects of industrial effluents on Allium cepa root meristem: A review on positive results and problems of effective compliance to environmental legislations; the Nigeria perspective

Most industries are sited with little or no consideration for environmental and social consequences, especially in developing countries. This has led to the discharge of genotoxic chemicals used for many purposes in the manufacturing processes into environmental compartments such as air, water, soil and sediments. Results of the cytotoxic and genotoxic assays of these wastewaters on Allium cepa root tip...

Effect of lead nitrate on survival rate and chronic exposure on growth performance of grass carp (Ctenopharyngodon idella)

The acute toxicity of lead nitrate to grass carp (Ctenopharyngodon idella) juveniles was assessed in a static renewal bioassay for 96 h. In addition, an experiment was conducted to determine the growth performance during 60-day sublethal (Pb(NO3)2) exposure. The results indicated that median lethal concentration (LC50) of lead nitrate to Grass carp for 96 h of exposure was 246.455 µ. The chronic exposure to...

Cytotoxicity and genotoxicity of some agropesticides used in Southern Africa

Pesticides use boosts agricultural yield by reducing crop losses. However, some pesticides are mutagens and active ingredients could produce different effects in different formulations. Wipe-out (WO) (Glyphosate 360 g/l), K-O Gard® (KOG) (Deltamethrin 10 g/l), Cutworm bait (CWB) (Sodium Fluosilicate, 100 g/kg), Snail ban (SB) (Metaldehyde, 30 g/kg and Carbaryl, 20 g/kg) and Coopex (CPX) (Permethrin 250...

Packaging type and their effects on the chemical and microbial quality of Sudanese white cheese (Gibna bayda)

The study was based on surveying ten samples of Sudanese white cheese packaged in two different containers (plastic and metal), collected from different supermarkets in Khartoum state. The comparison of chemical composition and microbial count was done. The experimental results showed that the average ash content, moisture, acidity, pH, and total solid content means were 7.00 ± 2.73, 45.00 ± 4.81, 0.85...
