In what experts call a worrying development, carbon monoxide has been among the two primary pollutants in Delhi’s air twice over the past week. The most common primary pollutant is PM (particulate matter) 2.5. CO is harmful as it reduces the blood’s capacity to carry oxygen to organs and tissues. At R K Puram, the level of CO at 10.30 pm on Sunday was 11.60 mg/m3. At Anand Vihar, it touched 11.70 mg/m3. The one-hour standard for CO is 4 mg/m3 and the eight-hour standard is 2 mg/m3.
Between May 2015 and October 2017, Delhi saw only two days of 'good' air quality, reveals Central Pollution Control Board (CPCB) data. Both the good air quality days were seen in July this year. Data shows that there has been a marginal improvement in air quality when it comes to the number of days that saw severely polluted and very poor air quality days. Between May 2015 and April 2016, the number of very poor air quality days was 116, and 15 of these were in the severe category.
EVEN THOUGH almost a year has passed since the Graded Response Action Plan to combat air pollution was put in place, a robust mechanism to measure air quality across NCR towns in Haryana and Uttar Pradesh is still incomplete. The action plan, formulated by the Supreme Court-appointed Environment Pollution (Prevention and Control) Authority (EPCA) last December, hinges on accurate air quality data from Delhi-NCR towns to suggest actions according to the concentration of pollutants.
Muck Rack makes it simple to find people, tweets, or articles that mention any name, keyword, company, hashtag etc. We've compiled this guide to help you make the most of your search.
Selecting a term
Start searching tweets, articles from media outlets, articles mentioned in tweets, journalists'
names, titles and bios with some suggested searches:
Companies or Topics (e.g. iPhone, Microsoft)
Phrases (e.g. "cloud computing") — use quotes to keep the terms together
Twitter handles (e.g. @username) — returns those who have mentioned or replied to
Names (e.g. "David Pogue")
Hashtags (e.g. #sxsw, #london2012)
Bio details (e.g. vegan, Olympics, father)
Muck Rack's Advanced Search allows for many boolean operators.
Find results that mention multiple specified terms, use AND or
+. For example, ensure each result contains both Elon Musk and Mark Zuckerberg by
searching Musk AND Zuckerberg or Musk + Zuckerberg.
Use the operators OR or , to broaden your search when you'd like either of
multiple terms to appear in results. (This is the default behavior of our search when no operators
are used). For example, results will contain either cake or cookie by searching cake OR cookie or cake,cookie
Use NOT or - to subtract results from your search. For
example, searching Disney will yield results about the Walt Disney Company as well as Walt Disney
World Resort. To exclude mentions of Disney World, search for Disney -World or Disney
When using one of these operators with a phrase, enclose it in quotation marks. For example, you can
find results about smartphones excluding Apple's iPhone 4S by searching smartphone -"iPhone
Exact case matching or punctuation
If you're searching for a brand name or keyword that relies on specific punctuation marks or capitalization, you can
find results that match your exact query by adding matchcase: before the keyword you're searching for, like matchcase:E*TRADE .
Use parentheses to separate multiple
boolean phrases. For example, to find journalists talking about having fun in Disney World or
Disneyland, search for ("disney world" OR disneyland) AND fun.
An asterisk can be used to search for any variation of a root word truncated by the asterisk. For example, searching for admin* will return results for administrator, administration, administer, administered, etc.
A near operator is an AND operator where you can control the distance between the words. You can vary the distance the near operation uses by adding a forward slash and number (between 0-99) such as strawberries NEAR/10 "whipped cream", which means the strawberries must exist within 10 words of "whipped cream".
