Contamination of the different components of environment through industrial and anthropogenic activities have guided new eras of research. This has lead to development of strategies/methodologies to curtail/minimize environmental contamination. Research studies conducted all over the globe established that bioremediation play a promising role in minimizing environmental contamination. In the last decade, phytoremediation studies have been conducted on a vast scale. Initial research in this scenario focused on screening terrestrial plant species that remove contaminants from soil and air. Later, scientific community realized that water is a basic necessity for sustaining life on earth and quality of which is getting deteriorated day by day. This initiated studies on phytoremediation using aquatic plants. Role of aquatic plant species in cleaning water bodies was also explored. Many of the aquatic plant species showed potential to treat domestic, municipal and industrial wastewaters and hence their use in constructed wetlands for treating wastewaters was emphasized. The present book contains five chapters. First two chapters provide information about types of contaminants commonly reported in wastewaters and enlists some important and well studied aquatic plant species known for their potential to remove various contaminants from wastewater. Subsequent chapters deal with mechanisms involved in contaminant removal by aquatic plant species, and also provide detailed information about role of aquatic plant species in wetlands. Potential of constructed wetlands in cleaning domestic and industrial wastewaters has also been discussed in detail. The strategy for enhancing phytoremediation capacity of plants by different means and effectiveness of phytoremediation technology in terms of monitory benefits has been discussed in last chapter. Last chapter also emphasizes the future aspects of this technology.
Heirs of the Land book represents the History of the Sikhs in a true spirit before the Mankind; and emboldens and encourage especially the Heirs of the Great Punjab, the Sikhs, to study their history, its people, and places those that had been ignored not only by the Indian and Pakistan States sponsored so-called Historians, but also, who are trying hard to dilute the Sikh Revolution of the SatGuru Nnak Sahib. Therefore, the author shall die in peace if this work inspires the historians to look at Harappa Civilisation and the Sikh-Revolution in its true inceptions. SatGuru Granth Sahib, the Living Guru of the Sikhs in the Globe proclaimed that the soul dwells in the body and imbue with SatGuru’s Shabad (the Ambrosial Nectar). We should purify our body in the contemplation of the SatGuru’s Shabad and eradicate Doubt Dubida duibDw; the Almighty Lord Giver of Peace Himself bestows His Mercy, Kirpa ikRpw, unites us with Himself: kwieAw ibrKu pMKI ivic vwsw] AMimRqu cugih gur sbid invwsw] (1068-17) KAA-I-AA BIRKHU PAnKHEE VICHI WAASAA.

Ever-changing environmental conditions and climatic transformations have affected each component of the environment. Increasing rates of soil, air and water pollution have altered the growth and production of vegetation to a greater extent and medicinal plants are also not spared from this. Medicinal plants form an important part of traditional and modern systems of medicine. The consumption of medicinal plants has increased over the last few decades. The present book provides detailed information on the topic with an emphasis on the effects of inorganic, organic (chemical), biological and other contaminants of medicinal plants. It provides a vast amount of information concerning the effects of various environmental factors on growth, productivity and secondary metabolite production in medicinal plants. The book also highlights the adverse effects of contaminants in plants and related toxicity of contaminated medicinal plants, with their possible effects on therapeutic efficiency and human health. The detailed information about the contamination and toxicity in medicinal plants will challenge the scientific community to find ways of countering many environmental adversities to protect, preserve and maintain many of the rare, highly valuable medicinal plants used in treating various diseases.
