Bioaccumulation of lead, mercury and nitrates of Macrobrachium rosenbergii (Shrimp) as indicator of water pollution in Iponan River, Cagayan de Oro

This study aimed to examine the mercury (Hg), lead (Pb), and nitrate (NO3) accumulation on Macrobrachium rosenbergii (shrimps) of Iponan River. The samples were analyzed using Cold Vapor Atomic Absorption Spectroscopy (CVAAS) for the heavy metals (Hg & Pb) and Bruccine Colorometric Method (BCM) for nitrate. One-way Analysis of Variance (ANOVA) and Standard Deviation analysis […]

Maternal blood lead levels and risk for low birth weight: a case-control study, Sidi Bel Abbes, Algeria

Several epidemiological studies have investigated high lead (Pb) exposure and pregnancy outcomes, but few studies have investigated the association of low lead exposure and low birth weight (LBW). The aims of this study were to estimate the maternal blood lead levels (BLL), to identify determinants for BLL among parturient woman and to evaluate the association […]

Investigation of cadmium (Cd) and lead (Pb) contents in soil, orange fruit and its accumulation in human blood

Heavy metals are among the most environmentally toxic substances. Cadmium (Cd) and Lead (Pb) are extremely toxic heavy metals and their presence in the soil poses severe danger to the food security and consequently human health. Present study was carried out to investigate the concentration of Cd and Pb in soil, Orange and human blood. […]

Damage to the environment is one of the major threats that humankind is facing today. Protection and preservation of the environment for sustainable development is the prime concern ahead of the human community. The study endeavors to assess the level of involvement of student leaders in the promotion of environmental education and protection. The aim […]

Estimation of blood lead level and its effect on hormonal responses of exposed men

The use of leaded gasoline play a major role in the air pollution in Iraq and most Asian countries that did not band the addition of lead to gasoline, also the increased use of private electricity generators contribute to the lead air pollution. In this study the blood lead level (BLL) of traffic policemen, national […]

Determination of lead biosorption efficacy of soilborne Achromobacter sp. through atomic absorption spectrophotometer (AAS) furnace

Rapid industrialization has been posed overall environment in jeopardy by discharging huge amount of industrial contaminants, mainly heavy metals into soil and water bodies. Among various heavy metals, lead is a major pollutant and it is necessary to eliminate from environment for minimizing the risk of uptake by plants, animal and human. In view of […]

Studying of some physical properties of screen printed of hazardous carcinogenic lead iodide thick films doped with aluminum

Lead iodide considers as one of the chemicals that is on the Special Health Hazard Substance List (SHHSL) and it is consider as carcinogenetic substance. In this study films of 12µm thick toxic PbI2 pure and doped with various atomic volumes doping concentration of Al (1, 2, 3, & 4 mil) were deposited, and their […]

Spore germination of silver fern (Pityrogramma calomelanos (L.) Link) using various lead (Pb) concentrations

Utilization of spores to screen potential of certain species of ferns is not new in the field of phytoremediation. However, for Pityrogramma calomelanos this is not yet done thus, in this study spores were used to investigate capability of this species to tolerate lead. This species has been documented to hyperaccumulate arsenic in the environment […]

Toxicity of lead (Pb) at pH 6.5 and 8.5 to the whiteleg shrimps Litopenaeus vannamei

Lead accumulation in the marine environment is the result of anthropogenic use. The precipitation characteristic of lead elevates the risk of this metal exposure to the benthic communities. The study aimed to access the influence of acidic and basic environment on the toxicity of lead to the benthic organism, the whiteleg shrimp L. vannamei through […]

Effect of lead stress on polyphenols, flavonoids, and proline contents in radish (Raphanus sativus L.)

Radish (Raphanus sativus L.) is a suitable modal plant for eco-toxicological studies due to its tolerance to various stresses, such as metallic and saline stress. Lead is a toxic and exogenous metal to plants, and its presence causes several disturbances in plant. This work consists to determine the effect of lead stress applied during two […]
