Abstract
Heavy metal pollution is a great threat to the environment. These metals are enters to the soil-plant environment
through anthropogenic sources. A survey study was conducted to assess the heavy metals contamination of soils,
plants and waters of Madina town of Faisalabad, Metropolitan area in 2010. Soil, plant and water samples were
collected in the vicinity of Faisalabad following 4 × 4 Km grids. Soil samples were taken from 0-15 cm and 15-30
cm depths and prepared for the determination of metals (Cd, Pb and Ni). Plant samples were also taken from the
same location and dried and digested in HClO4:HNO3 in the ratio of 1:3. AB-DTPA extract of soil, plants extract and
water samples was analyzed on Atomic Absorption Spectrophotometer (Model Thermo S series). The results of the
study showed the concentration of metals in Soils ranged from Cd (0.00-0.111 ppm), Pb (0.87-8.97 ppm) and Ni
(0.017-1.72 ppm) at 0-15 cm while Cd (0.00-0.88 ppm), Pb (0.43-6.77 ppm) and Ni (0.055-0.852 ppm) at 15-30 cm
respectively. Cd, Pb and Ni concentration in the plants ranged from 0.00-2.25 ppm 1.11-5.29 ppm and 1.51-4.96
respectively. Concentration of metal in the ground water ranged from Cd (0.00-0.06 ppm), Pb (0.10-11.10 ppm) and
Ni (0.03-0.05). The concentration Pb and Ni was below the permissible limits while concentration of Cd in waters and
plants above the permissible limits. Finally it was concluded that soil, plant and water of Madina town were in the
safe limits with respect to metals. The use of city effuent is increasing the level of metals into the soils that ultimately
contaminate the soils, plants and waters. So, it is suggested that city effuent must be treated for the detoxifcation of
metals before use in irrigation purposes for crops.

Introduction
Pollution of heavy metals directly and indirectly afects the
human health. Tese substances adversely afect the productivity of
soils, plants, animals and the entire environment if exceed certain
limits [1]. Since quantity of good quality of water for agriculture is
decreasing so, peoples are using raw city efuent for the production
of diferent crops especially for vegetables. Tis raw city efuent
contains lot of carcinogenic constituents like heavy metals, organic
pollutants, salts and pathogens. Even in low concentration in soil-water
system heavy metals persist for longer time in soil from where these
enter into food chain through plant uptake. Sources of heavy metals
pollution in environment are mainly derived from anthropogenic
in nature. Which include vehicle exhaust, tire wearing, weathering
street surfaces, power plants, coal combustion, metallurgical industry,
auto repair shop, chemicals plant, domestic emission, weathering of
building and pavement surface and atmospheric deposits. However,
the anthropogenic sources of heavy metals in agricultural soils include
mining, smelting, waste disposal, urban efuent, vehicle exhausts,
sewage sludge, pesticides and fertilizers application. Among all the
heavy metals cadmium (Cd) is a highly toxic for both the plants and
animals as well as for human beings. Cadmium enters into soil-plant
environment mainly through anthropogenic activities. Compounds
of Cd are more soluble than other heavy metals rendering it more
available for plant absorption where these could accumulate in edible
plant parts.
In Pakistan Cd concentration in soil samples from the Islamabad
expressway varied from 5.8 to 6.1 mgkg
-1
with an average value of 5.95
mgkg
-1
[2]. Te value of Cd in the paddy and straw was ranged from
0.116to 0.370 mgkg
-1
and 0.315 to0.370 mgkg
-1
in the areas of Faisalabad
[3]. Nickel (Ni) another heavy metal which is toxic, carcinogenic and
dangerous for humans, plants and animals. Te Ni released into the soil
from copper-nickle smelters, burning of diesel oil containing Ni, city
efuent, bio-solid, impurities in fertilizers, mining and smelting [4].
It enters into the soil-environment through anthropogenic activities
although small quantities are released during in-situ wheathering of
parent material. In soil samples from Islamabad expressway, average
concentration of Ni was 32 mg kg
-1
[2]. Chemical analysis of paddy and
straw from Sheikhupura contained Ni 0.073-0.093 mg kg
-1
[5].
Lead (Pb) is a widespread heavy present in soils, plants and waters.
It is mostly present in top layer of soil due to the deposition from air
containing smoke from vehicles. Te Pb is released to the from mining,
industrial and agricultural chemicals. In uncontaminated soils, Pb
concentrations are generally below 50 mg kg
_1
[6]. Te Pb concentration
in vegetation growing on such soils is ofen less than 10 mg kg
_1
dry
mass. Soil lead ranging from 10 to 293 mgkg
-1
in agricultural areas and
in the areas of pesticide manufacturing companies 57.05 mg kg
-1
were
noted in Rajasthan, area of India [7].
