Oil and Gas Treatment and disposal of wastewater from shale gas extraction Shale gas extraction produces large volumes of wastewater from hydraulic fracturing in addition to relatively small volumes of water from the formation (i.e., the geologic rock unit from which
All metal concentrations were generally higher in the dry season than in the rainy season in the three loions.28 This could be a result of evaporation which leads to concentration of the metals. Evapotranspiration in the study areas is higher than 100 mm, except in July and August.

2020/8/9· Chemical hazards in drinking-water The World Health Organization’s (WHO) Guidelines for drinking-water quality (GDWQ) cover a broad range of chemicals that can affect drinking-water quality. However, not all chemicals included in the GDWQ will be relevant within
Arsenic is a complex metal, that forms a variety of compounds, either inorganic or organic. Organic Arsenic compounds like Arsenobetaine, Arsenocholine, Arsenosugars and Tetramethylarsonium salts contain carbon and are mainly found in sea-living organisms, however occasionally they can be found in species living on land.
This study investigated the level of heavy metal contamination in soils at 0 to 10cm and 10 to 20 cm depths from twelve (12) sample loions in Kakuri industrial area of Kaduna, Nigeria. The phisco-chemical parameters such as organic matter content (OM), soil pH, calcium carbonate and particle size distribution of the soil samples were determined.
In a study on effects of occupational health hazards in Nigeria, only 10.83% of the fisherfolk were reported to be 50 years and above, revealing that the majority were in their active ages than the relatively old age. 49 Oyediran et al 50 also found that the majority of
Ball mills for superfine calcium carbonate ball mill classifier systems have been improved over time and are now capable of achieving much finer products in the past
The heavy metal Chromium was also high. Most of the physical and chemical parameters analyzed were higher in flood water than in Borehole and River Water but generally within allowable limits. Other challenges faced by the people included loss of houses, ponds, farmlands, traditional grounds and means of livelihood, destruction of herbs and vegetation, exposure to wild animals.
