Abstract— The present research was conducted to calculate levels of different heavy metals like Fe, Mn, Cu,
and Zn in leafy vegetables when grown with different water sources. The result showed quite high range of
accumulation when the vegetables were irrigated with wastewater. Wastewater irrigated vegetables showed
variations (115-377), (12-68), (5.2-16.8), (21-45) mg/kg for iron, manganese, copper and zinc. Highest toxic
level of iron and manganese were detected in mint and spinach and carrot showed highest value of copper and
zinc. From the present study we can conclude that the vegetables grown from these water resources will lead to
heavy metal accumulation in human body i.e. for both adult and children if they continuously consume these
vegetables. For this regular monitoring of these heavy metals is needed in order to prevent excessive metal
accumulation in the body. However the results obtained from the present study shows that the ranges of heavy
metal were below the permissible limit set by WHO/FAO.
Keywords— Heavy metals, vegetables, daily requirement, waste water effluent, human health.
I. INTRODUCTION
Due to easy availability of wastewater and scarcity of
freshwater, it is mostly used for irrigation of vegetables
1
.
Waste irrigation is thought to make a considerable
contribution to heavy wastewater. The metal content of the
soil are very harmful due their non- biodegradable nature
and they can easily get assemble indifferent parts of the
body. These metals are harmful because they can easily
dissolve in water.A small amount of these metals is harmful
because there is no proper method to remove these metals
from our body.Heavy metals find their use in many industrial
applications and so there are widely spread. Due to this
reason the available waste water have large unit of these
heavy metals in them as which when indirectly used for
irrigation severely effects human body
2
. Excess amount of
accumulation in agricultural land irrigated by wastewater
affects the food quality The metal requirement in our body is
obtained from the food and water that we consume and this
in turn directly exposes us from the entry of toxic heavy
metals. Vegetables are an important ingredient of human diet
that contains essentials nutrients like vitamins, minerals
dietary fiber and antioxidants

. Leaves from different plant
species such as perennial, annuals are consumed especially
in rural areas, and there has been an increased trend of the
consumption among the persons living in metro cities.
Vegetables which have leaves as edible part are an economic
source to ensure the micronutrient intake. Examples include
Cabbage, Cauliflower, Broccoli, Lettuce, Coriander, Spinach
and Turnip. Rapid industrialization and the use of natural
resources have increased the accumulation of toxic
substances like heavy metals in the soil. The required protein
and vitamin which are supplied by vegetables are best to act
against rough digestion and prevents constipation are
supplied by vegetables
