“…What we know about ancient human habits, religious beliefs, and cultural practices comes through preserved works of art and craftsmanship that are dispersed like a crystal bowl dropped on marble. To study, one must particularly gather these wayward fragments (Khan, 2011).…”

Pottery has different uses in its capacity, as it was used in different countries in ancient and medieval times which in the modern era is more focused as an art along with its utility. In this research article the main focus is to compare the pottery techniques as an art and its development historically in China and Pakistan. The ancient and medieval techniques of pottery remained similar in both the countries while both later patterns and approaches of poetry changed with the passage of time in both countries. As it is seen that the Chinese pottery become more rationalize and worked more with the modern technology but the Pakistan pottery retained its artistic approach in a better way. The methodological approach of this research article is to apply the qualitative research techniques with using the case of Pakistani and Chinese pottery craft. In the same way, the results of the research shows that Chinese pottery has been changed with the passage of time.

“…The debasement of water bodies leads towards the deficiency of clean and drinking water and furthermore loss of common frameworks [19]. Current water reserves are insufficient and deterioration of freshwater quality cause grave water shortage particularly in underdeveloped and developing nations along with Pakistan [20][21][22][23][24]. About 70% of extracted water consumed in irrigation practices [25].…”

Cities and towns are affected by the multi-dimensional industrial activities with semi-arid and arid environments which cause a substantial rise in environmental pollution specifically in aquatic areas. The current study estimated the water quality and related health impacts by the consumption of heavy metal contamination. Surface water samples (n = 52) were collected using systematic random sampling technique from semi-arid region along Chenab river of district Sialkot, Gujrat and Mandi-bahwal-din of Punjab, Pakistan. Different physio-chemical and biological parameters and various heavy metal concentration were investigated using standard procedures from the collected surface water samples. Different physio-chemical and biological parameters and heavy metals concentration especially arsenic (As) and chromium (Cr) were above the permissible value of World Health Organization (WHO) and the National Environmental Quality Standards (NEQs). Water quality index results reflected that water quality of all samples were very poor and not suitable for the purpose of drinking. The value of Hazard Quotient (HQ) for As was near the threshold level (HQ>1) and carcinogenicity of As and Cr was 1 × 10 −4 in adults and children was more than the permissible limit laid down by WHO. Anthropogenic activities combined with semi-arid weather of the area in relation with diverse and uncommon water features triggered heavy metal pollution. Inverse distance weighted analyst module of ArcGIS software has been used to generate the spatial distribution of water pollutants of constituents.

“…Local studies related to surface water arsenic are scarce (8) . Most of them are either related to drinking (11)(12)(13) or ground water (14)(15)(16) arsenic. The studies highlighting arsenic transport in irrigation water from each possible point of contamination and prediction of arsenic load transported to rice fields is of significant importance, before it becomes part of food chain above the permissible limits.…”

Background/Objectives: Irrigation water at Phuleli and Akram canals carry the waste of Hyderabad city and other places on the way to rice fields at lower part of Indus Plain. The long term use of arsenic contaminated irrigation water can accumulate arsenic in rice soils. This study evaluated total arsenic in irrigation water and transported load to rice sites, in addition to the arsenic concentration in main canals and waste sites on the way to Badin. Methods: Atomic absorption spectrophotometer equipped with hydride vapor assembly was used to analyze the arsenic concentrations in irrigation water. Findings: Currently, the irrigation water quality was generally within the permissible limits of FAO for rice. All types of wastes (14.62-37.2 µg L-1) entering the Phuleli and Akram canals (7.08 µg L-1) on the way contributed to total arsenic (6.30-57.12 µg L-1) in irrigation water at the entrance of rice sites. However, higher arsenic contamination in irrigation water was due to sugar industry waste (37.2 µg L-1) and lowest due to city waste of Badin (14.62 µg L-1). The data indicated that mean total arsenic concentration from irrigation water would load 0.12 and 0.14 mg kg-1 of arsenic annually in soils on the basis of net 1000 and 1300 mm a-1 water application to rice, respectively. Applications/Improvements: The results clearly indicated that waste added from different sources may aggravate the arsenic contamination of canal water and yet the accumulation in rice fields will keep on increasing. It is suggested that waste must be treated before releasing to prevent contamination of rice field.
