Plenty of studies have reported the immobilization behavior of Zn on biochars derived from different biomass (such as hardwood25,26, corn straw25, sugarcane straw27, dairy manure28, and meat and bonemeal29), and some of them have proposed the immobilization mechanisms which implied more important...
Particularly unusual was the fact that the protocols for this proposed national study, with its implications for public health, were initiated by the Ministry of Energy, which even suggested what a desirable mean blood lead level in the population might be [13]. Even when there was subsequently...

Agro-industrial waste’s continuous production and proper disposal are major environmental issues. Still, the improved nutritional value of these agro-industrial wastes is paving the way for these wastes to be valorized in animal/fish feed [48]. Jayan et al. [49] proposed this concept by valor...
For nutritional reasons, it is essential to search for sustainable vegetable sources of PUFAs, especially for α-linolenic acid from the n-3 family. The primary biological role of α-linolenic may consist of it being a substrate for long chain PUFAs in EPA and DHA synthesis [49,50]. Baker...
