“…Organophosphate residues negatively affect soil fertility due to the active ingredient contained so we need a residue analysis. Organophosphate residues were detected in different land use systems include the active ingredient diazinon, chlorpyrifos, profenofos, malathion and ethion operation which includes non-systemic active ingredient (Pandey et al, 2014). Profenofos concentration in horticultural dryland is high (Table 2) more than MRL, while diazinon, parathion, malathion, ethion, chlorpyrifos less than MRL.…”

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).

“…33 Thus the development of cost-effective and environmentally friendly technologies for the remediation of wastewater is of global interest. 33,34 Thus in our continued efforts in developing cost-effective analytical techniques [35][36][37][38][39][40][41][42][43] and uoride removal methods, 5,6 we were looking for the most cost effective method for uoride removal from aqueous samples. With the above background, this paper deals with the logical approach to evaluate the uoride removal efficiency of dolomite and evidences the ion-exchange mechanism of uoride uptake and the removal capacity of the thermally activated dolomite, an inexpensive and widely available geomaterial.…”

“…The adsorptions around 1463 and 1389 cm −1 were the various vibrational modes of -CH 2 and -CH 3 groups. The intense band at 1156 cm −1 was corresponding to the P-OCH 3 group, and the P-S bond was linked to 522 cm −1 (Pandey et al 2014). Compared to NIP, the band changes in intense and width at 3564 and 1732 cm −1 should be attributed to the formation of hydrogen bond between malathion and MAA.…”

“…There are methods that have been developed for assessing malathion residues, such as kinetic spectrophotometric method (Pandey et al 2014), biosensor (Raghu et al 2014), gas chromatography (GC) (Lofty et al 2013), high-performance liquid chromatography (HPLC) (Tsiropoulos et al 2006), gas chromatographymass spectrometry (GC-MS) (Chowdhury et al 2013), flow injection-tandem mass spectrometry (FI-MS/MS) (Nakazawa et al 2004), and high-performance liquid chromatography-mass spectrometry (HPLC-MS) (Sobhanzadeh et al 2011). The traditional cleanup procedures for assessment of malathion residues include liquid-liquid partition (Lofty et al 2013), SPE (Sanchez-Brunete et al 2005), and matrix solid-phase dispersion extract (Nieto-García et al 2015).…”

Malathion is an organophosphorous insecticide for controlling insects on fruits and vegetables, miscellaneous household insects, and animal parasites. It is important to develop highly efficient and selective pre-treatment method for analyzing malathion residues in environment and samples from agricultural products based on the molecularly imprinted polymers (MIPs). In this study, we developed a tailor-made MIP method with highly specific recognization to the template. The MIPs were prepared using malathion as a template, methacrylic acid (MAA) as a functional monomer, ethylene glycol dimethacrylate (EGDMA) as a crosslinker, azodiisobutyronitrile (AIBN) as an initiator, and the acetonitrile-chloroform (1:1, v/v) as a porogen. The molecular recognization mechanism of malathion and MAA was evaluated by molecular simulation, ultraviolet spectrometry (UV), and (1)H-nuclear magnetic resonance ((1)H-NMR). MAA interacted specifically with malathion by hydrogen bond with a ratio of 2:1. The MIPs exhibit a high affinity, recognition specificity, and efficient adsorption performance for malathion. The Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), surface area and porosimeter analyzer, thermogravimetric/differential thermal analyzer (TG/DTA) were used to characterize the properties of MIP. The malathion residues in soil, tap water, and cabbage were cleaned up by MIP-SPE, detected quantitatively using GC-FPD, and confirmed by GC-MS/MS. The limits of tap water, soil, and cabbage were confined to 0.001 mg L(-1), 0.004 and 0.004 mg kg(-1), respectively. The spiked recoveries of malathion were 96.06-111.49% (with RSD being 5.7-9.2%), 98.13-103.83% (RSD, 3.5-8.7%), and 84.94-93.69% (RSD, 4.7-5.8%) for tap water, soil, and cabbage samples, respectively. Thus, the method developed here can be used effectively in assessing malathion residues in multiple environmental samples. The aim of the study was to provide an efficient, selective, and accurate method for analyzing malathion at trace levels in multiple media.
