“…Ion H + contained in chemical fertilizer substitutes the inorganic pesticides molecul so the adsorption is decreased (Odukkathil and Vasudevan 2013). Continuous flooding desreases organophospate residue concentration because of leaching (Manuaba, 2009;Wu et al, 2011). Residue mobillity increasing due to irigation (Muller et al 2007) especially on the topsoil (Scholtz and Bidleman 2006) so the residue concentration decreased.…”

The use of inorganic pesticides result in residues of pesticides in the environment. Mojogedang is an area that has implemented a system of organic farming but also there are farmers who apply chemical pesticides. Pesticides are commonly used by farmers in Mojogedang causing residues, such as organophosphate. Organophosphates contains the active ingredient with a relatively long persistence in the environment and dangerous that it needs a study to investigate the organophosphate residues. The aims of this research to study the level of organophosphate residue and their exposure to soil properties in a variety of land uses in Mojogedang (paddy field, dryland, community forest). This study to analize organic-C, pH, soil texture, total microbia and organophosphate residues including diazinon, parathion, profenofos, ethion, chlorpyrifos, malathion. Data was analized statistically using correlation analysis. Results of this study show that all residue consentration of organophosphate residues active ingredients in organic paddy field soil, inorganic paddy field soil, dryland soil, community forest soil less than maximum residue limits (MRL) 0,05 mg/kg. Residue levels of horticultural dryland with profenofos active ingredient more than MRL (62,060 mg/kg) while the other active ingredient less than MRL. Soil texture is a soil property which closely correlate with organophosphate residues in the soil (sand fraction r = -0,601, dust fraction r = -0,658, clay fraction = -0,509).

“…Currently, soil pollution by heavy metals is widespread (Calisi et al, 2013;Garg et al, 2009). The accumulation of heavy metals and organic pollutants (e.g., pesticides) in earthworms is speciesdependent (Garg et al, 2009;van Vliet et al, 2005;Wu et al, 2011). Garg et al (2009) reported that Cr and Pb concentrations were significantly higher in Allolobophora parva compared with Eisenia fetida, whereas accumulation of Zn was similar in both species.…”

Laboratory experiments were conducted to determine the effects of soil aluminum levels and moisture content on aluminum (Al) bioaccumulation and protein content in the earthworm (Octodrilus complanatus). The experimental design was a completely randomized block with 2 factors (aluminum content [C-0: 0 mg kg -1 , C-1: 1000 mg kg -1 , C-2: 2000 mg kg -1 , C-3: 3000 mg kg -1 ] and moisture level [M1: 100% of soil water capacity, M2: 60% of soil water capacity] and 3 replications. The lowest pH was noted in the C-0 treatment. There were no significant differences in the electrical conductivity, cation exchange capacity or total nitrogen in soil between the aluminum treatments. Moreover, there were no significant differences in soil properties between the moisture treatments. The highest soil Al content was noted in the C-3 treatment. No earthworm mortality was observed in soil contaminated with Al. Moreover, the highest aluminum content in earthworms was observed in the C-3 treatment. The aluminum content in the earthworms was significantly positively correlated with the aluminum content in the soil (r=0.984***, p<0.001). Our results indicated that the growth of earthworms was affected by the Al level. Lastly, Al caused a reduction in earthworm protein content.

“…A CaCl 2 solution is usually considered to be a "soft" extraction method for the labile fraction of chlorimuron-ethyl in soil (Barriuso et al, 2004); for example, it provided an indication of the amount of chlorimuron-ethyl that could be desorbed or that was water soluble and exchangeable. A mixture of aqueous solution and organic solvent, such as PBS-M, was expected to measure the fraction of chlorimuron-ethyl bound to soil organic matter (SOM) (Wu et al, 2011). As shown in Fig.…”

Bioavailability is a critical factor for assessing the environmental risk of organic pollutants in soil. In this study, extractions with 3 different solvents, including 2 aqueous solutions, calcium chloride (CaCl 2 ) and a phosphate buffer solution (PBS), and a mixture of aqueous solution and organic solvent, a PBS-methanol (8:2, volume/volume) mixture (PBS-M), were performed to assess the bioavailability of chlorimuron-ethyl in soil in comparison to a battery of toxicity tests in wheat seedlings. The results indicated that the peroxidase (POD) activity in wheat leaves after 7 d of exposure was one of the sensitive biomarkers of chlorimuron-ethyl in soil. The extractability of chlorimuron-ethyl by all the 3 solvents decreased with exposure time, and the rate of decrease of the PBS-M extraction between 1 and 7 d of exposure was substantially higher than those of the aqueous solution extractions. Chlorimuron-ethyl gradually changed from a water-soluble form into a soil organic matter (SOM)-bound form in the soil. The PBS extraction correlated best with the POD activity in the leaves after 7 d of exposure. Key Words:chemical extraction, environmental risk, organic pollutants, organic solvent, peroxidase activity, phosphate buffer solution, toxicity test
