Quantum dots exhibit less bioaccumulation than free cadmium and selenium in the earthworm Eisenia andrei
This work addresses the bioaccumulation behavior of cadmium selenide quantum dots (QD) by Eisenia andrei earthworms in a terrestrial environment. Earthworms were exposed to QD‐treated soil for up to four weeks, and analyzed for cadmium and selenium concentration using inductively coupled plasma mass spectrometry. Results were compared to earthworms exposed to cadmium nitrate and selenious acid, ...

Leaching of heavy metals from wastewater sludge, using a thermostatted column
We have previously patented a process for the extraction of toxic and valuable metals from foundry sands using a thermostatted column. In this paper, we describe a similar device for the removal of toxic metals from wastewater sludge. The wastes were finely ground and suspended in an aqueous pulp, and 10-40g of mineral acid or sodium hydroxide were added to reach a pH of 2, 5, 7 and 10, together ...

Leaves of Lolium multiflorum as indicators of airborne trace element distribution in Central Italy
Ambient air contains particles, ranging from sub-micrometric aerosols to clearly visible dust and sand grains. Plants during evolution developed the ability to maximise light interception and CO2 assimilation and also the efficiency to collect the airborne pollutants. Therefore, plant tissues have been used as indicators of trace elements air pollution. Lolium multiflorum leaves were used as a ...

Qualitative analysis and classification of surface water in Bukit Merah Reservoir in Malaysia
An attempt was made to analyze and classify water quality at the Bukit Merah Reservoir (BMR) in Malaysia to determine the degree of pollution and ascertain the required treatment level before usage. Parameters determined included; pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), ammoniacal nitrogen (NH3-N), suspended solids (SS), total nitrogen (TN) and ...

Heavy metal speciation and mobility assessment of arid soils in the vicinity of Al Ain landfill, United Arab Emirates
Sixty-four surface soil samples taken in the vicinity of Al Ain landfill were analysed for cadmium, chromium, copper, nickel, lead and zinc by inductively coupled plasma spectroscopy. Extraction techniques were used to establish the association of the total concentrations of the six metals in the soil samples with their contents in the exchangeable, carbonate, iron/manganese oxides, and residual ...

Heavy Metals Water Testing Powered by DNA
Water pollution is a worldwide problem affecting developing and developed countries alike. Heavy metal contaminants are one prevalent type of water pollutant. They are persistent in the environment once d is charged and removal from source waters is necessary to ensure a clean drinking water supply. The problem of heavy metal pollution arises from several sources. Heavy metals such as uranium can ...

Assessment of levels and “health-effects” of airborne particulate matter in mining, metal refining and metal working industries
The increased awareness of occupational health, hygiene and safety in recent years has resulted in improvement of working conditions and in reducing workers’ exposure to many toxic substances. However, substantial hazards remain, the number of cases of occupational illness due to hazardous exposure is still high, and new cases will continue to occur if there are no further improvements. During ...

Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory
ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...

Comparing Field Portable X-Ray Fluorescence (XRF) To Laboratory Analysis Of Heavy Metals In Soil
ABSTRACT Field portable x-ray fluorescence (XRF) continues to gain acceptance as a complement to traditional laboratory testing of metal contaminated soil. The quality of data produced by field XRF varies with site conditions, soil composition, and sample preparation. Quality assurance protocols for the field method usually require that a number of field samples be split and sent to a ...

Analyzing sulfur in soil and sediment with handheld XRF
Background Sulfur creates more than nasty odors. Exposure to low levels (0-10ppm) of hydrogen sulfide (H2S) causes irritation of eyes, nose, and throat; higher levels can cause headaches, dizziness, nausea and vomiting, coughing, and breathing difficulty. H2S and numerous other odor-causing compounds are generated as a result of organic material decomposition. In the case of the Muddy River in ...
