Matlamat kajian ini adalah untuk menilai potensi risiko, simptom pendedahan racun makhluk perosak dan kaitannya dengan pengetahuan, sikap dan amalan para petani dengan kadar kepekatan sisa racun makhluk perosak (RMP) di dalam medium air. Kajian keratan rentas ini telah dijalankan di Kampung Permatang Keriang, Seberang Perai Utara, Pulau Pinang, Malaysia. Sejumlah 38 daripada 119 petani telah terlibat dalam sesi kaji selidik ini. Kelulusan etika juga diperolehi daripada Jawatankuasa Etika Penyelidikan Manusia dengan nombor rujukan [Ref: USM/JEPeM/279.3]. Penilaian risiko kesihatan kimia (Chemical Health Risk Assessment, CHRA) telah dijalankan terhadap 16 responden dengan memilih empat jenis racun makhluk perosak yang paling kerap digunakan iaitu buprofezin, chlorpyrifos, difenoconazole dan lambda cyhalothrin. Semasa penilaian risiko kesihatan kimia (CHRA), parameter sampel persekitaran seperti halaju udara, suhu persekitaran, kelembapan, karbon monoksida, karbon dioksida dan tahap debu di samping parameter sampel air seperti oksigen terlarut, pH, suhu air dan kekeruhan telah direkodkan. This study aims to assess potential risks, exposure symptoms of pesticides and their relationship with farmers’ knowledge, attitude and practices (K.A.P) and pesticide concentration levels in water samples. This cross-sectional study was conducted in Kampung Permatang Keriang, Seberang Perai Utara, Pulau Pinang. A total of thirty-eight farmers out of one hundred nineteen were involved during the questionnaire session. Demographic information, knowledge, attitude and practices of farmers were collected during questionnaire sessions. Ethical approval was obtained from Human Research Ethics Committee USM [Ref: USM/JEPeM/279.3]. Chemical health risk assessments (CHRA) were conducted to sixteen respondents by choosing four different pesticides that frequent used by farmers which were buprofezin, chlorpyrifos, difenoconazole and lambda cyhalothrin. During CHRA, environmental samples in terms of physical air parameters such as air velocity, ambient temperature, relative humidity, carbon monoxide, carbon dioxide and dust level as well as in-situ water parameters such as dissolve oxygen, pH, water temperature and turbidity were collected.
