This paper aims to provide information about the fractions of cadmium (Cd) and its distribution in surface sediment collected from bivalves harvesting areas in Binh Thuan province (Tuy Phong, Phan Thiet, Lagi). For this purpose, the sediment samples were collected monthly along with these areas in 2015–2016. To analyze the fractions of Cd, a five-step Tessier (1979) sequential extraction process was used, including Fraction 1 (Exchangeable), Fraction 2 (Bound to carbonate), Fraction 3 (Bound to iron-manganese oxide), Fraction 4 (Bound to organic compounds), and Fraction 5 (Residual).

This paper aimed to determine the grey water footprint (GWF) of geothermal water resources and to investigate the effect of biochar adsorption on grey water footprint in Southeastern Turkey. In this paper, GWF has been calculated in terms of iron (Fe), arsenic (As), manganese (Mn), boron (B), and chrome (Cr) concentrations for fifteen observation geothermal resources located in Southeastern Anatolia Region. In this study, a new approach based on the GWF was developed in order to determine the geothermal water pollution.

Aquaculture in the coastal zone has contributed significantly to economic development in Giao Thuy district, Nam Dinh province. Therefore, water quality for aquaculture plays a vital role in sustainable aquaculture production. In this paper, iron (Fe) and manganese (Mn) concentrations in aquaculture coastal water of Giao Thuy district were analyzed during the rainy season (September 2017, August 2018) and dry season at low tide.

The study discussed the inner-sphere complexation between arsenic species and active surface metal (hydr)oxide NPs, which is attributed to the high selectivity toward arsenic species over other common ions (such as sulfate and chloride). In addition, the As(III) removal involving an oxidation process using oxidant oxides such as manganese oxide, zero valent iron and titanium oxide for enhancing adsorption performance was provided.

In this study, we aimed to use ferrate as an all-in-one alternative for the removal of chlorine-consumed compositions such as organic, color, turbidity, iron, and manganese in river water for water supply purposes. Ferrate (FeO42-) was simultaneously employed as coagulant and oxidant for purification of Saigon River water in order to reduce the formation of disinfection byproducts in the produced tap water.

Nine typical pedons from Langate Block of Kupwara district during 2017 were selected and surveyed for the purpose of collection of soil samples. The soil samples processed and analyzed for different nutrients. Available Micro and Macro nutrients were determined using standard techniques. The overall results showed that the soils are near slightly acidic to moderate alkaline in reaction, low to medium in organic carbon. In general the soils The available nutrients Nitrogen and Potassium were low to medium with the mean values of 287.99 and 149.

Micronutrients are essentially as important as macronutrients to have better growth, yield and quality in plants. The requirement of micronutrients (boron, iron, copper, zinc, manganese, magnesium and molybdenum) is only in traces, which is partly met from the soil or through chemical fertilizer or through other sources.

This study investigated the current situation of groundwater use for domestic purposes and consumption. The research team collected data from several centralized water supply stations operated by the CERWASS. The team also conducted surveys and took water samples from 94 households and water supply stations. The evaluation of groundwater quality and its suitability for domestic use was also conducted. The results showed that in terms of raw water quality, most of the samples had low iron (Fe) concentration and pH value.

Soil quality is one of the important factors controlling yields of the crops. Soil characterization in relation to evaluation of fertility status of the soils of an area or region is an important aspect in the context of sustainable agricultural production. Soil physicochemical parameters are more important that control its quality. Variation in nutrient supply is a natural phenomenon and some of them may be sufficient whereas others deficient.
