Dissipation processes of 14C-carbofuran in soil from Northwest Morocco as influenced by soil water content, temperature and microbial activity

  In order to predict the fate of carbofuran in soil, this study was undertaken to evaluate the influence of soil temperature, soil moisture and soil microbial activity on mineralisation and dissipation rate of carbofuran on a typical sugar beet clayey soil of Loukkos area (Northwest Morocco). Results of incubation studies showed that soil temperature and soil water contents have great influence on...

Baseline, spatial and temporal variation of total suspended particulate (TSP) matter in Isoko land

  In this article, a link is being established between the low life expectancy in Nigeria and the ubiquitous suspended particulate matter as the most common form of air pollutants in Nigeria. Consequently, the baseline, spatial and temporal distributions of total suspended particulate (TSP) airborne particles in Isoko land with numerous oil wells and flow stations have been quantified. Airborne...

Assessment of direct soil pollution in automobile junk market

  Crude recycling of used engines and transmissions in no small measure is of great concern to environmental health and safety. In this study, topsoil across Obosi automobile junk market (alias Mgbuka Obosi) near Onitsha, Nigeria, is investigated for heavy metal and polycyclic aromatic hydrocarbon (PAH) enrichment. Fifteen composite soil samples were randomly collected in addition to the background samples at...
