“…The higher concentrations of toxic metals recorded in sampling positions within the quarry site con rm the relationship between metal concentrations and distance from the quarry, which is in good agreement with the report of Ekpo et al (2012).…”

This study investigated the anthropogenic impacts of quarrying activities on the ecosystem. Soil, rock, water, and plant samples were collected at varying distances around a quarry site located in Ijebu North local government area of Ogun State, Nigeria. The physicochemical properties were determined using standard methods, and metal quantification was done using Inductively Coupled Optical Emission Spectrometry (ICP-OES). The results of physicochemical properties of the sampled soil include: pH (7.20–8.74), bulk density (0.922–1.198 g/cm³), and moisture content (26.3–34.1%). Turbidity is 56.3 higher than the WHO standard, while alkalinity is 144. The physicochemical properties of the water samples all fall within the permissible limits set by the WHO except for alkalinity, turbidity, hardness, suspended solids, and COD. The results of metal analysis (mg/kg) are as follows: ≤9.94, ≤ 3961.77, ≤ 11.07, ≤ 244.03, ≤ 111.77, ≤ 251.19, ≤ 262.84, ≤ 101.23, ≤ 3094.87, ≤ 2816.07, ≤ 235.78, ≤ 182.72 for Ag, Al, As, B, Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, and Pb, respectively, in all the environmental samples. High levels above the WHO permissible standard of toxic metals under study were found in rock samples, and these are statistically similar to the levels recorded in soil samples close to the quarry site. Additionally, high levels of Al, Cd, Cr, Cu, Fe, and Mn above the WHO limit were recorded in plant and water samples close to the quarry site. Quarry activities in the study site have a negative impact on the soil, plant, and water body around the site, and this needs to be checked on time before it degenerates into an environmental catastrophe.

“…However, with such a level of mechanical exploration of the mineral deposits in the area, the environmental and health consequences may have been considered a matter of concern. Quarrying activity provides a large tone of chippings of various sizes, as well as accompanying toxic wastes that affect both the environment and humans (Ekpo et al, 2012).…”

“…Shakir and Mohamed (2013) stated that quarrying has resulted in an increase in infrastructural and mineral resource development in several regions.However, Moibi (2007) stated that quarrying causes soil compaction, landscape degradation, soil erosion, and loss of vegetation and soil fauna. Similarly, Ekpo et al (2012) enumerated the destruction of wildlife and biodiversity, loss of fertile soil, air and water pollution, degradation of farmland, impairment of human health, forced pollution migration, and damage to aquatic ecosystems as negative impacts of quarrying on the environment. Several studies (Ekpo et al, 2012;Ezenwa et al, 2014 andTiimub et al, 2015;Nwogha et al, 2017) have reported increase in heavy metal content of soil and plant because of quarrying activities.…”

This study evaluates the environmental risks of quarrying activities in the Marksino Concession area, Akampka, with a focus on heavy metal contamination of the soil. Soil samples were collected at various distances from the quarry site and analyzed using atomic absorption spectrophotometry (FAAS; PG990) to determine concentrations of lead, chromium, copper, cadmium, cobalt, nickel, arsenic, and zinc. Pollution indices and ecological risk factors were calculated, along with hazard quotients and indices for non-carcinogenic impacts on children and adults. Results indicate that contamination values for all metals were below one, suggesting no significant impact at the sampling points. The geo-accumulation index values also indicated no significant impact for all metals. Furthermore, hazard quotient (HQ) and hazard index (HI) values for all metals were below the permissible value of 1, indicating non-carcinogenic risks for residents. However, children showed higher HI values compared to adults, emphasizing the need for targeted measures to protect this vulnerable group. Continuous monitoring and mitigation efforts are crucial for sustainable quarrying activities and prevention of environmental hazards in the Marksino Concession area.

“…The bioaccumulation of heavy elements varies according to species, ages, and organisms [6]. Active vital organs are the organs in which most heavy metals accumulate, such as the liver, kidneys, and gills [7,8]. The current study aimed to study the accumulation of heavy elements (cadmium, copper and zinc), in three tissues of the grass carp fish (gills, muscles and viscera), with a study of the concentrations of elements (cadmium, copper and zinc) in general water and sediment.…”

The current study was conducted in Thi Qar Governorate, Nasiriyah city on one of the private farms, grass carp were cultured, to determine the effect of some heavy elements (cadmium, copper and zinc) in the water and sediments of the Euphrates River, measuring the concentration of elements in some parts (gills, muscles and viscera) of grass carp fish. Water, sediment and fish samples were collected monthly from 11/8/2022 to 4/8/2023. The study also included field tests such as air and water temperature measurements, the air temperature ranged between 11-29 C, and the water temperature ranged between 9-25 C. Heavy metals were measured in water, sediment and fish tissues by flame atomic absorption spectrometer. The results showed the highest total concentration of cadmium in the water during April and copper in February and April, as for zinc, it recorded the highest concentration during April. The highest concentration of cadmium was recorded in the gills and muscles during April. The highest concentration of cadmium in the guts was recorded in the winter. Copper had the highest concentration in the gills and muscles during April. Zinc recorded high concentrations in the viscera, muscles and gills. As for the sediments, the values of cadmium ranged from 0.104-0.223 μg/L. Copper recorded values ranging between 5.07-13.2 μg/L. Zinc values ranged between 29.87-59.2 μg/L. The results showed that the accumulation of heavy elements was as follows: Concentrations in the water of zinc>cadmium>copper. Concentrations in the sediments of zinc> copper>cadmium. In tissues: Cadmium viscera>gills>muscle. gillscopper>viscera>muscles. Viscera>gills>muscles.
