TL;DR: In this article, two eco-friendly substances, natural manganese ore and agricultural waste cornstalks, were selected as raw materials to prepare biochar-based composite catalyst (MCC) for removing bisphenol A by activating peroxymonosulfate (PMS).

TL;DR: Wood charcoal was chosen as the best material for endosulfan removal because the study of physical and chemical characteristics of wood charcoal revealed that it is a potential adsorbent and can be improved further.
Abstract: In the present study, an attempt was made to select a low cost adsorbing material for the removal of endosulfan [C,C'‐(1, 4, 5, 6, 7, 7‐hexachloro‐8, 9, 10‐trinorborn‐5‐en‐2,3‐ylene)(dimethylsulphite)] from water. Various low cost adsorbents like wood charcoal, kimberlite tailings, silica, macro fungi sojar caju were tried with activated charcoal as reference material. The above materials were selected from various sources encompassing organic, inorganic, clayey, and biological sources. For the selection of suitable adsorbent for endosulfan uptake, maximum adsorption capacity (Qmax) was chosen as the parameter. Kinetic profiles of removal were generated for all the materials to assess the equilibrium time. Equilibrium studies were carried out for all materials to assess the adsorption equilibrium model that they followed. The model that gave the best correlation coefficient by linear regression analysis, was adopted for the calculation of Qmax of the corresponding adsorbent material. Using linear...

TL;DR: Health hazard assessment showed no health risk from exposure to Pb, As, Cd, and Hg by consuming fish from this lake, but Hg concentration was higher, suggesting that heavy metal pollution problem in fish from Nansi Lake still exists.
Abstract: Metal accumulation in fish is a global public health concern, because the consumption of contaminated fish accounts for the primary exposure of humans to toxic metals. In this study, the concentrations of arsenic (As), cadmium (Cd), lead (Pb), and mercury (Hg) in Crucian carp (Carassius auratus),Yellow catfish (Pelteobagrus fulvidraco), and Bighead carp (Hypophthalmichthys nobilis) from Nansi Lake of China were evaluated, and compared with the corresponding historical values in 2001 when the government started to govern water environment effectively. Bioaccumulation of heavy metal was highest in P.fulvidraco, followed by C.auratus and H.nobilis. The concentrations of Pb, As, Cd were much lower than the historical values, but Hg concentration was higher, suggesting that heavy metal pollution problem in fish from Nansi Lake still exists. Health hazard assessment showed no health risk from exposure to Pb, As, Cd, and Hg by consuming fish from this lake.

TL;DR: In this article, the engineering characteristics and microstructure formation pattern of magnesium phosphate cement (MPC) mortar by adding bentonite clay (BC) were investigated, where consecutive dosages of BC were added in place of magnesia for preparing the surrogate specimens and kept in two static curing conditions like air and water for comparing the target objectives.
