ABSTRACT
The paper investigates effects of detergent for domestic use on the photosynthetic activity and chlorophyll content in intact bean leaves. The plants were watered for 21 days with a solution of domestic washing powder of 0.60 g r/l. It was established that the activity of photosynthetic apparatus in the plant leaf PhACNorm [%] decreases exponentially with the length of plant treatment/watering. At the end of the treatment (21st day) the activity of photosynthetic apparatus in the dosed plant leaf was no more than 45% of that in control plant (those which were not watered with detergent solution). With increased plant treatment duration the changed chlorophyll concentration ΔChlNorm [%] rose non-linearly in plant leaves. The highest change ΔChlNorm [%] was observed on the 21st day and amounted to 12%.
