HOUSE HOLDS WASTE WATER EFFECTS ON MEDICINAL PLANT (ACHILLEA SANTOLINA L.) AND SOIL CHARACTERISTICS Abdul Malik1*.

Irrigation with wastewater is identified as a significant contributor of heavy metals to the soil. Extreme buildup of heavy metals in cultivated soils by untreated waste water could not finish in soil impurity, on the other hand also impact on food purity and security. This study was conducted to assess the comparative effects of households waste waters on physio-morphological, biochemical and growth characteristics of medicinally important plant species; Achillea santolina L. For this objective plants were grown in botanical garden university of Balochistan Quetta, irrigated by four different types of water including municipal waste water, semi-treated and completely treated waste water and ground water. Results of this investigation indicated that the incessant usage of polluted water for irrigating porpoises led to the enhancement of micro-nutrients as well as heavy metals in the soil. Our results also showed significant variation in the physiological, biochemical and growth characteristic of Achillea santolina L. with respect to different water treatments. Per plant biomass and total yield/ per plant was found nonsignificant higher in waste water plants as compared to the ground and treated waters plants. Similarly rate of translocation and uptake of heavy metals were also found maximum in plants grown in waste water as compared to other waters. On the other hand the plants irrigated with treatment water produced more secondary metabolites and antioxidants, as compared to the ground and untreated waste water. Among the heavy metals, Zn and Mn showed highest uptake and between the plant parts (leaves and flowers) the maximum uptake was noted in leaves then flowers. The more production of metabolites and antioxidants might be enhance the remedial activities of Achillea santolina L. and reduced the uptake of heavy metals contents moreover it increase the tolerant efficiency of pants against the negative impact of heavy metals and thus not improve the yield and biomass potential in plants irrigated by treated waste water. Keywords: Polluted water, Achillea santolina L., Heavy metals uptake, physio-morphological, biochemical and growth characteristics
