“…One explanation for the higher mass emissions from the poplar pellet combustion may be the different ratio between wood and bark compared to standard softwood pellets. Moreover, poplar trees generally take up metals more efficiently than most other trees (Ruttens et al 2011). This might cause the evaporation of excess metals into the emissions.…”

Wood pellets have been used in domestic heating appliances for three decades. However, because the share of renewable energy for heating will likely rise over the next several years, alternative biomass fuels, such as short-rotation coppice or energy crops, will be utilized. We tested particulate emissions from the combustion of standard softwood pellets and three alternative pellets (poplar, Miscanthus sp., and wheat straw) for their ability to induce inflammatory, cytotoxic, and genotoxic responses in a mouse macrophage cell line. Our results showed clear differences in the chemical composition of the emissions, which was reflected in the toxicological effects. Standard softwood and straw pellet combustion resulted in the lowest PM 1 mass emissions. Miscanthus sp. and poplar combustion emissions were approximately three times higher. Emissions from the herbaceous biomass pellets contained higher amounts of chloride and organic carbon than the emissions from standard softwood pellet combustion. Additionally, the emissions of the poplar pellet combustion contained the highest concentration of metals. The emissions from the biomass alternatives caused significantly higher genotoxicity than the emissions from the standard softwood pellets. Moreover, straw pellet emissions caused higher inflammation than the other samples. Regarding cytotoxicity, the differences between the samples were smaller. Relative toxicity was generally highest for the poplar and Miscanthus sp. samples, as their emission factors were much higher. Thus, in addition to possible technical problems, alternative pellet materials may cause higher emissions and toxicity. The long-term use of alternative fuels in residential-scale appliances will require technological developments in both burners and filtration. EDITORTiina Reponen

“…The adsorption and complexation of As through the application of beringite could therefore be the major factors contributing to the concentration of As-EDTA compared to the control. A decrease of 34 % in extractable arsenic in contaminated soil has similarly been obtained and attributed to the presence of bivalent cations (Ca 2+ and Mg 2+ ) in beringite that aid in the adsorption of arsenic (Ruttens & Boulet, 2011;Saha, 2014).…”

The effects of zeolite and beringite ( 0, 30 and 60 kg ha -1 w/w) on EDTA-extractable Arsenic (As), water soluble As, and bioavailability of arsenic (As) in non-mined agricultural soil and tailings of a mined site(capped and uncapped) were studied in a pot experiment. Un-amended non-mined agricultural soil was included as a control. EDTA-extractable and water extractable forms of As were monitored for 0-12-weeks after amendments and bioavailability of As was evaluated by growing lettuce (Lactuca sativa) on amended tailings/soil for 4-12 weeks after incubation. For EDTA-extractable As at week 12, beringite amendment (60 kg ha -1 (w/w) was 29 %, 8.6 % and 26 % more efficient over zeolite for soil/capped and uncapped tailings respectively. For water-extractable As at week 12, beringite amendment 60 kg ha -1 (w/w) again recorded 84 %, 54.5 % and 72 % less extractable As over zeolite in soil/capped and uncapped tailings respectively. Analysis for bioavailable-As in edible leafy aerial parts of lettuce, indicated 52.5 %, 82.0 % and 39.0 % less extractable As for beringte over zeolite in capped and uncapped tailings (week 12, 60 kg ha -1 (w/w)... Beringite (week 12, 60 kg ha -1 w/w) reduced As of capped tailing (0.3 mg kg -1 ) below the FAO & WHO recommended maximum limit of 1.0 mg kg -1 for human consumption.

In detoxification, the plant takes up the contaminant of concern from soil, water, or a mixture of both, converts it to a volatile form, and releases it to the atmosphere, usually through the leaf stomata. This technique is only suitable for contaminants that do not pose a significant air pollution hazard. Contaminants taken up by the roots pass through the roots to the leaves and are volatized through stomata where gas exchange occurs. This experimental work examines the ability of transgenic Arabidopsis thaliana with P4502E1 gene from rabbit to detoxify for many soil contaminants. The P450 2E1 enzyme controls the rate-limiting step in the metabolism of multiple environmental pollutants. The percentage of transformation increased at the less diluted cultures of Agrobacterium tumefaciens. The ability of transgenic plants were tested for their potential in remediation of metals such as Sodium (Na), Magnesium (Mg), Potassium (K), Calcium (Ca), Manganese (Mn), Iron (Fe), Copper (Cu), Zinc (Zn), and Nickel (Ni). In the present work, transgenic plants were more efficient achieving 31, 46, 42, 48,33, 51, 35,29 and 39% contribution of each to the total value of detoxification contaminants.
