This study examined the toxicity potential of total suspended particulate in the airshed of a haulage vehicle park located in a major highway connecting Lagos, the commercial centre of Nigeria to its other parts. It has an approximate area of 0.6 km2. Ambient air total suspended particulates (TSP)...

Particulate matter is one of the most important indoor air pollutants involved in a number of adverse health effects, such as premature deaths and increased mortality of infants and other parts of sensitive population. This paper focuses on investigation of metal substances of suspended as well as...

The Mn and Pb of the total suspended particulates (TSP) in totally 95 1-h samples and As, Cd, Mn, Ni and Pb in totally 29 24-h samples have been determined by flameless graphite furnace atomic absorption spectrophotometry. The monthly TSP for July 1992 contained Mn and Pb 0.033 and 1.25‰ in downtown...

Several epidemiological studies have shown an association between particulate air pollution and health effects. Suspended particulates and more specifically the inhalable PM10 fraction appear to cause respiratory health effects and heart diseases. Furthermore, particulate pollution is of paramount...

Some amounts of inert products are given into environment due to biological degradation of substrate in activated sludge system. The effluent of biological wastewater treatment consists of inert substrate in influent flow, soluble microbial products and non degradable or slowly degradable organic...
