Dairy Milk

Vegetables and dairy milk are important commodities in Pangalengan and Lembang, West Java. However, agrochemicals are used intensively and excessively in production system. Therefore, pesticide residues and contamination commonly occurred in agricultural products and environments. The study aimed to assess farmers’ attitudes on pesticide toxicity and reducing pesticide residues in animal and food crops products, and investigate the attitude changes of farmers on pesticide use. It was an on-farm research and farmers were directly involved in the study. The attitude change was analyzed on questionnaire and interview base for over 99 respondents in Pangalengan and Lembang between 2001 and 2003. Samples of soils, weeds, cabbages and milk were collected for pesticide residue analysis. Results showed that farmers did not aware on toxicity effects of pesticides in both animal and human health. There was misinterpretation among the farmers where pesticides were regarded as drugs rather than toxic compound to increase productivity. The organochlorines/OCs (lindane and heptachlor) were common pesticide contaminants found in soils of 7.9- 11.4 ppb, but no organophospates (OPs) were detected. Both OCs and OPs were also detected in soils of Lembang at a range of 11.53-65.63 ppb and 0.6-2.6 ppb, respectively. There were pesticide residues detected in weeds collected from Pangalengan (8.93 ppb lindane, 2.05 ppb heptachlor, and 33.27 ppb chlorpyriphos methyl/CPM and Lembang (6.45 ppb lindane, 2.65 ppb endosulfan, 6.85 ppb diazinon, and 0.5 ppb CPM). Only endosulfan with least residue level (0.1 ppb) was detected in organic cabbages, whereas lindane was detected much higher (3.7 ppb) in non-organic cabbages. Pesticide residues were not detected in milk of dairy cattle fed on by-products of organic cabbages, but lindane was still present in milk of dairy cattle fed on non-organic cabbages for 7 days subsequently. The present study indicates that the organic farming practice may reduce pesticide residues in animal and agricultural products. Farmers appreciated that pesticides may cause residual effects on their products (95.2%) and affected public health and environment (92.9%). Therefore, they were willing to convert their agricultural practices to organic farming (69.1%).

Organochlorine Pesticide Residues

Determination of organochlorine pesticide residues in shrimp is very important to ensure the consumer’s safety and to fulfill the importer’s demand. Therefore, a simple and efficient multiple organochlorine pesticide residues analytical method using quick, easy, cheap, effective, rugged and safe (QuEChERS) extraction technique and Gas Chromatography coupled with Electron Capture Detector (ECD) has been developed and validated for the determination of 19 organochlorine pesticides (α- BHC, δ- BHC, β- BHC, γ- BHC, Heptachlor, Aldrin, Heptachlor Epoxide, γ- Chlordane, α- Chlordane, α- Endosulfan, 4,4 DDE, Dieldrin, Endrin, 4,4 DDD, β- Endosulfan, 4,4 DDT, Endosulfan sulphate, Methoxychlor, and Endrin Ketone) in shrimp. The method was validated by evaluating the accuracy, precision, linearity, limit of detection (LOD) and limit of quantification (LOQ). The average recoveries of the selected pesticides ranged from 84% to 106% with RSDr ≤ 14% in four fortification levels of 0.05, 0.1, 0.2 and 0.3 mg kg-1. The linearity was ≥ 0.996 for all of the selected pesticides with matrix matched calibration standards. The LOD ranged from 0.003 to 0.009 mg kg-1 and the LOQ was 0.05 mg kg-1. This method was applied successfully for the residue analysis of 40 shrimp samples collected from different regions in Bangladesh.SAARC J. Agri., 16(1): 81-93 (2018)

Leaves And Roots

In the present study emphasize on phytochemical screening in leaves and roots of Barleria prionitis Linn. The extract of plant materials total ash content, extractive value, water soluble ash, and loss on drying values were identified. Medicinal plant materials are liable to contain pesticide residues, which accumulate from agriculture practices, such as spraying, treatment of soils during cultivation and administration of fumigants during storage. It is therefore recommended that every sample of medicinal plants used for such type of studies should be analyzed for the pesticidal residues. Therefore in the present study parts of the herb used for their antidiabetic potential were analyzed for organochlorine pesticides, which are persistent and remain in the food chain for longer periods. The samples of leaf and root of Barleria prionitis were ground coarsely and then preceded for the extraction procedure. The sample of extracts were analysed for residues of organochlorine pesticides by Gas Chromatography (GC). Analysis were carried out on a Schimadzu Model 2010 Gas Chromatograph (GC) equipped with 63 NI electron capture detector (ECD) and a capillary column HP ultra 2. The instrument was supported by Lab Solution software. The pesticide residues detected in them in the GC were within the limits. For phytochemical screening, the ethanolic and hydroalcoholic extracts obtained were prepared and subjected to various qualitative tests in order to reveal the presence or absence of common phytopharmaceuticals by using standard tests. Keywords: Phytochemical screening, Pesticidal residues, Barleria prionitis Gas Chromatography, Ash value, extractive value.
