Among of 200 respondents, 47 (23.5%) had history of skin diseases and 20 (10%) respiratory conditions while 37 (18.5%) reported to have reproductive problems. The skin diseases reported were skin itching and rashes 29 (14.5%), black spots on the skin 12 (6.0%) and scabies 6 (3.0%).

The factors that were associated with exposure status were existence of source of pollutants that pollutes river Msimbazi (p=0.010), number of years that respondents spent in occupation (p=0.016), ignorance of respondents on the use of personal protective equipments such that apron was (p=0.013), overall (p=0.043) and sunglasses (p=0.013). Variables such as age less than 35 years (p=0.034), distance less than 0.5 kms in proximity from river Msimbazi (p=0.005) were significantly associated with skin diseases. Female respondents (p=0.005), nature of respondents occupational for survival (p=0.048) were significantly associated with respiratory conditions while respondents education level (p=0.000), existence of source of pollutants that pollutes river Msimbazi (p=0.002) were significantly associated with reproductive problems.
