Abstract
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.
